BACKGROUND 1. Technical Field

The present disclosure relates to a monitoring system and a monitoringmethod which display an imaging video related to an incident using aplurality of imaging videos that are imaged by an imaging device.

2. Description of the Related Art

In recent years, monitoring cameras are widespread which are utilizedfor crime prevention or the like by imaging prescribed indoor andoutdoor monitoring areas in respective positions such as variousfacilities, buildings, factories, houses, and roads. In addition, inorder to support works of police officers or security guards,examination is progressed for an operation of imaging videos of a sitein such a way that the police officers or the security guards on dutywear or possess wearable cameras or in such a way that in-vehiclecameras are mounted in patrol cars or security vehicles. For example, ina police station, examination is performed on an operation of extractingimaging videos related to an incident as incident videos from videosimaged by imaging devices, such as the monitoring cameras, the wearablecameras, and the in-vehicle cameras, and using the extracted imagingvideos for investigation. In addition, support of disposition of thepolice officers or the security guards using the imaging video imaged bythe monitoring cameras and the like is under examination.

For example, Japanese Patent Unexamined Publication No. 2009-206617discloses a crime prevention system using face authentication. In thecrime prevention system of the patent document, face authentication ofan investigation target subject is performed by collating imageinformation imaged by a fixed camera device with facial information inan investigation target subject list database at an investigationmanagement server, whereabout information of the investigation targetsubject is sent to a wireless base station, which is specified usingpositional information and time information in a case where it ispossible to specify the investigation target subject, a security officeterminal is specified based on positional information of a mobile phoneterminal in a case where facial information transmitted from the mobilephone terminal is collated with authenticated facial information and thepieces of facial information coincide with each other, and a fact thatthe investigation target subject is present near is notified to thesecurity office terminal.

In addition, Japanese Patent Unexamined Publication No. 2007-158496discloses a map interconnection video monitoring method and a device.The map interconnection video monitoring method and the device in thepatent document calculate a range, in which a criminal may run, at everyfixed time after an incident occurs, store video data from monitoringcameras installed in a plurality of places, calculate an expectedpassing time slot, through which the criminal passes, from the videodata of the plurality of places corresponding to the range in which thecriminal may run, and display video data in the expected passing timeslot on a screen together with map data.

Here, it is conceivable that an incident is investigated and analyzedusing imaging videos in an in-station system of a police station or asecurity company. Here, in a case where, for example, it is possible tocompare and examine a plurality of incident videos which are acquiredfrom different sources such as different camera angles (imaging places),locations, and times, the method and a device are effective toinvestigate a cause of the incident.

In the example according to the related art disclosed in Japanese PatentUnexamined Publication No. 2009-206617, it is possible to acquire piecesof image information from the plurality of fixed camera devices andmobile phone terminals, and to use the acquired image information forthe face authentication.

Microphone 118 inputs voice, which is produced by the police officer orthe person in charge in the site, or sounds of atmosphere around thesite. For example, in a case where the police officer or the person incharge performs a report to command center 101 or performs communicationwith a terminal of another police officer or another person in chargeusing voice, microphone 118 collects and inputs voice of the policeofficer or the person in charge, and outputs voice data to CPU 111through I/O controller 112. In addition, in a case where moving imagesare imaged by capture 158, microphone 118 collects and inputs peripheralsounds, and outputs the voice data to CPU 111 through I/O controller112. CPU 111 sends the input voice data to the center device, theserver, or another site terminal using communicator 113.

Capture 158 includes an imaging lens and a solid-state imaging deviceformed of a Charge Coupled Device (CCD)-type image sensor or aComplementary Metal Oxide Semiconductor (CMOS)-type image sensor.Capture 158 images a subject of a site, and outputs acquired image dataof the subject to CPU 111 through I/O controller 112. For example, in acase where atmosphere around a police officer in a site is imaged bymobile terminal 110 or wearable camera 150 or in a case where aprescribed monitoring area of the site is imaged by monitoring camera130, capture 158 acquires video data of the imaged moving images orstill images and outputs the video data to CPU 111. CPU 111 sends theinput video data to the center device, the server device, or anothersite terminal using communicator 113.

GPS receptor 119 receives satellite signals, which are sent from aplurality of GPS transmitters (for example, four navigation satellites)and include respective signal sending hours and position coordinates,and outputs the received satellite signals to CPU 111 through I/Ocontroller 112. CPU 111 calculates current positional coordinates ofmobile terminal 110, wearable camera 150, or in-vehicle camera system140 and reception hours of the satellite signals using the plurality ofsatellite signals. Meanwhile, the calculation may be performed by GPSreceptor 119 instead of CPU 111. CPU 111 sends the acquired positionalinformation of the site terminal, such as mobile terminal 110, to thecenter device, the server device, or another site terminal usingcommunicator 113. Meanwhile, information of the reception hour of thesatellite signal may be used to correct a system hour of the siteterminal. The system hour is used for recording or the like of imaginghour of the imaged images (including still images and moving images).

First Exemplary Embodiment

An incident video display process of the police work support system willbe described as a first exemplary embodiment. A system which performsthe incident video display process according to the exemplary embodimentmay be formed as a monitoring system according to the presentdisclosure. In addition, it is possible to prescribe a process procedureof the monitoring system as a monitoring method according to the presentdisclosure. In the first exemplary embodiment, a process procedure ofdisplaying a plurality of incident videos is illustrated.

FIG. 5 is a sequence view illustrating an example of an operationprocedure of the incident video display process according to the firstexemplary embodiment. In the exemplary embodiment, a procedure isillustrated in a case of accumulating incident videos, which arerelevant to an incident occurred within police jurisdiction and areimaged by site terminal 180, such as monitoring camera 130, wearablecamera 150, mobile terminal 110, or in-vehicle camera system 140, incontent management server 10, and displaying the incident videos oncenter device 80 such as client PC 70.

In FIG. 5, in a case where an incident occurs, site terminal 180 imagessubjects around the site, and records imaged video data (S11).Furthermore, in a case where a police officer or the like, who is auser, performs a video registration manipulation (S12), site terminal180 sends the video data of an imaging video to content managementserver 10 through network 161, and registers the imaging video (S13).The video registration manipulation performed by the user ismanipulation input of ending recording in a case where imaging isperformed by wearable camera 150, and the video registrationmanipulation performed by the user is manipulations input of endingrecording, sending the recorded video, and the like in a case whereimaging is performed by mobile terminal 110 or in-vehicle camera system140. In addition, in a case where imaging is performed by monitoringcamera 130, the video registration manipulation is manipulation input,such as downloading of the recorded video using center console 60 orclient PC 70 performed by the user of command center 101. Meanwhile, itis possible to register the imaging video in content management server10 by coupling site terminal 180 to network 165 in the police stationthrough a Universal Serial Bus (USB).

In a case where content management server 10 receives video data to beregistered from site terminal 180, content management server 10preserves the video data of the imaging video in storage 18 (S14).Furthermore, content management server 10 preserves incident informationrelated to the imaging video (S15). The incident information includes,for example, a name of a person who is related to an incident, anincident occurrence place, time, an incident management number, anincident type, and the like. Content management server 10 constructs anincident video database by associating the video data of the imagingvideo with the incident information and preserving the resulting videodata as an incident video in storage 18.

Center device 80 is capable of displaying an incident video displayscreen, which realizes an incident video display interface, on display76 and displaying the incident video according to a user manipulation.Center device 80 inputs prescribed key information, which is used toextract the incident video, to content management server 10 based oninput of a search word performed by a police officer or a person incharge, who is the user, in the command center 101 or input ofinformation corresponding to a specific incident from the site terminalor the in-police station terminal (S16). In a case where contentmanagement server 10 receives the key information from center device 80,content management server 10 performs a process of searching for theincident video preserved in storage 18, and extracts an incident videocorresponding to the prescribed key information as a moving imagecandidate (S17). That is, content management server 10 extracts arelevant incident video using the key information as a common item.Furthermore, content management server 10 outputs video attributeinformation of the extracted moving image candidate to center device 80(S18). In a case where center device 80 receives the video attributeinformation of the moving image candidate, center device 80 displays themoving image candidate of the incident video on display 76 (S19).Subsequently, based on moving image candidate selection manipulation anddisplay mode selection manipulation performed by the user, center device80 sends moving image selection instruction (S20) of the incident videoand display mode selection instruction (S21) to content managementserver 10. In a case where content management server 10 receives themoving image selection instruction and the display mode selectioninstruction from center device 80, content management server 10 outputsthe video data of the selected incident video and incident information(S22), and outputs a display screen corresponding to the selecteddisplay mode to center device 80 (S23). Center device 80 displays theincident video display screen, which is output from content managementserver 10, on display 76 (S24).

FIG. 6 is a view illustrating a first example of the incident videodisplay screen. The first example is an example of a display mode whichenables a plurality of incident videos to be arranged and displayed on amap of a prescribed region within the jurisdiction according to a resultof search for key information of a person.

Incident video display screen 300 of the first example includes mapinformation 301 and video-related information 302 disposed on a left endportion of the screen. On the map of map information 301, it isillustrated that a plurality of incident videos are recorded. Video mark303 which indicates an imaging place and video attribute information304, which includes an imaging date and an imaging hour, an imagingcamera (Camera 01 or the like), and a location (Place 1 or the like) ofthe imaging place, are displayed for each of the incident videos. In alower part of video attribute information 304, video reproduction button(View Video) 306, which instructs to perform reproduction display of theincident video, is provided. In video mark 303, a facial image of theinvestigation target subject, which is included in the incident video,is displayed as a thumbnail image. The investigation target subjectcorresponds to a person who is extracted as a result of search for theperson according to designation of the key information of the person bythe user. The example of the drawing illustrates a case in which “JAMESSMITH” is searched as an example of the key information of the personand the video attribute information of the incident video, in which theperson is imaged, is arranged and displayed on the map. In addition, ina case where there is path information of movement locus of theinvestigation target subject as the incident information based on thepositional information of the site terminal acquired when the policeofficer possesses mobile terminal 110 or wearable camera 150 and chasesthe investigation target subject, center device 80 is capable ofacquiring the path information of the movement locus and displayingmovement locus 305 on the map of map information 301.

In video-related information 302, the imaging date and the imaging hour,the imaging camera (Camera 01 or the like), the location (Place 1 or thelike) of the imaging place, and the name and the facial image of theperson who is being imaged are displayed as a list for each incidentvideo. In a case where a plurality of people are imaged in one incidentvideo, one or more names and facial images of a representative personare displayed.

In FIG. 5, in a case where reproduction button manipulation is performedfor a video reproduction instruction in such a way that the user selectsa specific video from the plurality of incident videos and performspressing manipulation on video reproduction button 306 (S25), centerdevice 80 sends a video data request to content management server 10(S26). In a case where content management server 10 receives the videodata request, content management server 10 reads the video data of theselected incident video from storage 18 and outputs the video data(S27), and delivers the video data to center device 80 (S28). Centerdevice 80 reproduces and displays the delivered video data, therebyperforming reproduction of the moving images of the incident videoselected by the user (S29).

As described above, in a case where a person corresponding to theinvestigation target subject is searched for as the key information, itis possible to extract common incident videos related to a specificperson and comprehensively display the extracted incident videos on themap, and to reproduce and display an incident video selected by theuser. Therefore, it is possible to collect and display incident videosof highly-relevant different sources and to check a relationship betweenthe plurality of incident videos, and the user can effectively andaccurately grasp a situation of an incident.

FIG. 7 is a view illustrating a second example of the incident videodisplay screen. The second example is an example of a display mode whichenables a plurality of incident videos to be arranged and displayed on amap of a prescribed region within the jurisdiction according to a resultof search for key information of an incident. Here, difference from thefirst example illustrated in FIG. 6 will be mainly described.

Similarly to the first example, incident video display screen 310 of thesecond example includes map information 311 and video-relatedinformation 312 disposed on a left end portion of the screen. On the mapof map information 311, video mark 313 which indicates an imaging place,video attribute information (an imaging date and an imaging hour, theimaging camera, a location of the imaging place, or the like) 314, andvideo reproduction button 316 are displayed for each of the plurality ofincident videos. In video-related information 312, an imaging date andan imaging hour, an imaging camera (Camera 01 or the like), a location(Place 1 or the like) of an imaging place, an incident number(ACCIDENT#1 or the like), and a video number (Video 1-1 or the like) aredisplayed for each incident video as a list. Meanwhile, a representativeimage of each incident video may be displayed as a thumbnail image. Inaddition, the plurality of incident videos, which are displayed in therespective imaging places, may be simultaneously operated and reproducedby manipulating video reproduction button 316. The example of thedrawing illustrates a case in which “ACCIDENT#1” is searched for as anexample of the key information of the incident number and videoattribute information of an incident video, in which the incident isimaged, is arranged and displayed on the map.

As described above, even in a case where searching is performed using anincident number of an investigation target as the key information, it ispossible to extract common incident videos related to a specificincident and comprehensively display the extracted incident videos onthe map, and to reproduce and display an incident video selected by theuser, similarly to the case of a person. Therefore, it is possible tocollect and display incident videos of highly-relevant different sourcesand to check a relationship between the plurality of incident videos,and thus the user can effectively and accurately grasp a situation ofthe incident.

It is possible to check a situation of asite in more detail by arranging and simultaneously displaying videoswhich are acquired by imaging a scene at the same place in the same hourfrom different angles. The plurality of incident videos which aresimultaneously displayed are displayed by extracting videos fromseparate angles of the same place, videos in the same hour of differentplaces, or the like.

In first incident video 331 and second incident video 332, sub-screendisplays are respectively provided, and thus it is possible to displayenlarged display videos 351 and 352 acquired by enlarging parts in thevideos. In a case where, for example, the user designates a specificperson in incident videos 331 and 332 which are simultaneouslydisplayed, a video corresponding to a part which includes the designatedperson is enlarged and displayed as the enlarged display videos 351 and352. Meanwhile, it is possible to designate a plurality of people andenlarge and display the designated people. In lower parts of firstincident video 331 and second incident video 332, time display bars 341and 342, which indicate recording time (a recording start hour and arecording end hour) of the respective incident videos 331 and 332, andreproduction indicator 343 which indicates a current reproductionposition (reproduction time), are displayed. In addition, a videoreproduction button 345, which is used to instruct reproduction start,temporary stop, and reproduction end of the incident video, is provided.In the example of the drawing, an example is illustrated in which movingimages in the same hour, in which a time slot common to the recordingtime exist, are synchronized and reproduced in the plurality of incidentvideos which are simultaneously displayed.

As described above, it is possible for the user to easily and accuratelygrasp a situation of an incident by collecting and displaying incidentvideos of highly-relevant different sources. In particular, it ispossible to check a situation of an incident site in more detail byarranging and, synchronizing, and displaying a plurality of incidentvideos of different sources related to a common incident or a person,and thus it is possible to effectively investigate a cause of theincident. Therefore, it is possible to improve accuracy of inspection orinvestigation of the incident.

In the exemplary embodiment, with respect to the plurality of incidentvideos, which are extracted to correspond to the prescribed keyinformation, video attribute information related to the incident videois superimposed on the map information based on the positionalinformation of the imaging place, the video attribute information isdisplayed in the imaging place on the map of the map information, andthe correspondent incident videos are reproduced and displayed.Therefore, the incident videos of highly-related different sources arecollectively and visually recognized, and thus it is possible torecognize the relationship between the plurality of incident videos andit is possible for the user to effectively and accurately grasp thesituation of the incident.

In addition, in the exemplary embodiment, the plurality of pieces ofvideo attribute information are arranged and displayed on the map.Therefore, it is possible to effectively compare and check the pluralityof highly-related incident videos through contrast.

In addition, in the exemplary embodiment, the movement locus of theperson corresponding to the prescribed key information is displayed onthe map of the incident video display screen, and thus it is possible toeffectively check a relationship between an action history of theinvestigation target subject which is highly relevant to the incidentand the incident video.

In addition, in the exemplary embodiment, the thumbnail image related tothe incident video is displayed on the map as the video attributeinformation to be displayed in the incident video display screen, andthus it is possible to recognize features of a person imaged in theincident video or an outline of the incident video at a glance.

In addition, in the exemplary embodiment, the plurality of incidentvideos, acquired by different input sources which image the samelocation, are simultaneously displayed and the incident videos aresynchronized, reproduced, and displayed. Therefore, it is possible tocheck a situation of an incident site in more detail and it is possiblefor the user to effectively investigate a cause of the incident.

In addition, in the exemplary embodiment, in a case where the incidentvideo is displayed, an enlarged display video, which is acquired byenlarging a part of the incident video, is displayed. Therefore, it ispossible to visually recognize a specific person or a part, whichattracts attention of the user, in detail.

Second Exemplary Embodiment

A police officer disposition support process of the police work supportsystem will be described as a second exemplary embodiment. A systemwhich performs the police officer disposition support process accordingto the exemplary embodiment may be formed as a guidance system. Inaddition, it is possible to prescribe a process procedure in thedisposition work support system as a guidance method. In the secondexemplary embodiment, a process procedure of supporting dispatch of apolice officer in a case where an incident occurs is illustrated.

FIG. 9 is a sequence view illustrating an example of an operationprocedure of a police officer disposition support process according tothe second exemplary embodiment. The exemplary embodiment illustrates aprocedure of sending an instruction from center device 80, such asclient PC 70, to site terminal 180, such as mobile terminal 110 usingPolice disposition server 20 and device management server 40 in a casewhere an incident occurs within the police jurisdiction, and supportingdisposition of a police officer who becomes a dispatched person.

In FIG. 9, in a case where an incident occurs and notifications of theincident, such as reports or testimonies from a citizen who is a witnessor reports from a police officer, are received in command center 101(S41), center device 80 sends positional information of an incidentoccurrence location to Police disposition server 20, and registers atarget place of police disposition to Police disposition server 20 basedon a position of an incident occurrence location (S42). Here, centerdevice 80 displays a police disposition screen, which includes mapinformation within the jurisdiction, on display 76. The police officeror the person in charge in the command center 101, who is a user ofcenter device 80, sets the target place by referring to a policedisposition screen displayed on display 76 and designating an incidentoccurrence location on the map. It is possible to input positionalinformation of the target place by acquiring from witness informationusing a Record Management System (RMS) provided in, for example, thepolice station system based on notification content of the incident, byacquiring through voice recognition of report content, or by performingmanual input of the user of center device 80. A location name or anaddress of the target place is displayed in the police dispositionscreen. Police disposition server 20 registers the target place, andrecords incident information related to incident content, such as anincident type and a degree of danger, together. Furthermore, Policedisposition server 20 sends information of the target place to devicemanagement server 40, inquires about terminal information of the siteterminal, and instructs to collect information (S43).

Device management server 40 maintains a terminal ID and positionalinformation of the site terminal, and grasps a current position of eachsite terminal. Meanwhile, device management server 40 may inquire of thesite terminal about the positional information each time, and mayacquire the positional information. Device management server 40 narrowsdown site terminals which are close to the target place using thepositional information of the target place (S44), and requests pieces ofpositional information of the respective terminals with respect to somenarrowed-down site terminals (S45). Site terminal 180 which receives therequest for the positional information acquires current positionalinformation according to satellite signals which are received by GPSreceptor 119 (S46), and returns positional information of each terminal(S47). Device management server 40 notifies Police disposition server 20about terminal information which includes positional informationacquired from each site terminal 180 (S48). The terminal informationincludes an terminal ID of the site terminal, positional information,and a police officer ID (information of a police officer who is a userof the terminal) which is bound to the terminal ID. The policeinformation as an example of information of a dispatched person may bemaintained in the site terminal or may be managed by being maintained indevice management server 40. Meanwhile, device management server 40 orPolice disposition server 20 may maintain day shift information whichincludes a work schedule of the police officer and a dispositionschedule such as a responsible allocated area in advance, and mayassociate the terminal ID of the site terminal with police informationand manage the terminal ID of the site terminal.

Police disposition server 20 delivers police positional information of apolice officer who is close to the incident occurrence location and mapinformation to center device 80 based on terminal information acquiredfrom device management server 40 (S49). In a case where center device 80receives the police positional information and the map information,center device 80 performs display by superimposing a position of thepolice officer on the map in the police disposition screen (S50).

Policedisposition screen 400, acquired in a case where a target position isregistered when an incident occurs, includes map information 401 andincident-related information 402. On the map of map information 401,target place mark 415 which indicates a position of the target placewhere the incident occurs, and police marks 421, 422, and 423 whichindicate positions of police officers are illustrated. The example ofthe drawing illustrates that a traffic accident occurs as an incident ina location of Address #1 and three police officers police 1, police 2,and police 3 are present in the vicinity of the target place. In policemarks 421, 422, and 423, thumbnail images of facial images of therespective police officers are displayed. In a case of the trafficaccident, a name of a witness (person involved in the accident), avehicle number, a vehicle type (a name of a type of the vehicle), andthe like are displayed in incident-related information 402.

In FIG. 9, in a case where center device 80 receives manipulation input,which designates a police officer, from a police officer or a person incharge who is a user in the command center 101, center device 80 sendsselection input of the police officer to Police disposition server 20(S51). Police disposition server 20 calculates a path which reaches thetarget place with respect to the selection input of the police officerbased on a current position of the designated police officer, andcalculates a needed distance and a needed time until arriving at thetarget place (S52). Furthermore, Police disposition server 20 deliversthe police disposition information related to the designated policeofficer as dispatched person disposition information, which includes aname of the police officer, current positional information, a neededdistance and a needed time up to the target place, to center device 80(S53). Center device 80 displays the police disposition informationreceived from Police disposition server 20 on the police dispositionscreen (S54).

FIG. 11 is a view illustrating an example of the police dispositionscreen in a case where the police disposition information is displayed.In police disposition screen 420 in a case where the police dispositioninformation is received, police disposition information 431 is displayedto correspond to police mark 424 of the designated police officer(police 4 in the example of the drawing). In police dispositioninformation 431, a name of the police officer (MIKE), a current position(Place #5) of the police officer, a needed distance (Distance), and aneeded time (Time) are displayed. In addition, in a lower part of policedisposition information 431, an inquiry button (REQUEST FOR MISSION) 432is provided to inquire whether or not to directly rush to the targetplace of the incident site. In addition, on the map of map information401, path information 437 from the current position of the policeofficer to the target place is displayed. In addition, in an upper rightpart of police disposition screen 420, a streaming video of incidentvideo 435, which is acquired by imaging an incident occurrence locationby monitoring camera 130, wearable camera 150, or the like, isdisplayed. In an upper part of incident video 435, recording button(RECORD CASE) 436 which instructs video recording is provided.Meanwhile, incident video 435 may be displayed in such a way that Policedisposition server 20 interconnects with content management server 10,searches for imaging images in the target place, and acquires theimaging video in the incident occurrence location which coincides withthe search condition.

In FIG. 9, in a case where a manipulation of pressing inquiry button 432with respect to the police officer designated by the user is performedand a manipulation is performed on an inquiry button in order to input adispatch inquiry (S55), center device 80 sends an instruction for directrush request check to the police officer to Police disposition server 20(S56). In a case where Police disposition server 20 receives theinstruction for direct rush request check from center device 80, Policedisposition server 20 sends the direct rush request check to siteterminal 180 which is possessed (used) by the designated police officerthrough device management server 40 (S57 and S58). Here, Policedisposition server 20 sends incident-related information related to theincident which occurs in the target place to site terminal 180. In acase where site terminal 180 receives the direct rush request check,site terminal 180 displays an inquiry screen which notifies that theincident occurs and the direct rush request check with respect to thetarget place is performed (S59).

FIG. 12 is a view illustrating an example of the inquiry screen which isdisplayed on the site terminal. In inquiry screen 450, incident-relatedinformation 451 relevant to the incident which occurs in the targetplace and acceptance button (ACCEPT) 453 which receives an inquiry withrespect to the direct rush request check with respect to the targetplace are displayed. In incident-related information 451, an incidenttype (TYPE), a degree of danger (DANGEROUS), a location (LOCATION), aneeded distance (DISTANCE), and the like are displayed. In addition, animaging video related to the incident occurrence location (ordinarystill images, or still images or moving images of a current imagingvideo) may be displayed as incident-related information 451. The policeofficer views inquiry screen 450, which is displayed on display 116 ofsite terminal 180, selects acceptance or rejection with respect to thedirect rush request check, and performs manipulation to press acceptancebutton 453 in a case of acceptance.

In FIG. 12, in a case where an acceptance manipulation is performed insuch a way that the police officer who possesses site terminal 180performs a manipulation to press acceptance button 453 (S60), siteterminal 180 sends an acceptance message to Police disposition server 20through device management server 40 (S61 and S62). In a case wherePolice disposition server 20 receives the acceptance message from siteterminal 180, Police disposition server 20 transmits the acceptancemessage, which is received from designated police officer, to centerdevice 80 (S63). Center device 80 displays the received acceptancemessage on the police disposition screen (S64). Meanwhile, in a case ofa configuration which enables direct communication, communicationbetween Police disposition server 20 and site terminal 180 may beperformed by directly transmitting and receiving inquiry and responsewithout device management server 40. In a case where security isconsidered, secrecy is more increased in a case where site terminal 180is capable of communicating with only device management server 40. Inaddition, instead of an instruction to site terminal 180 through a usermanipulation performed on the police disposition screen displayed ondisplay 76, center device 80 may input a command using a voice of a userusing microphone 78 and may send the instruction to site terminal 180.

FIG. 13 is a view illustrating an example of the police dispositionscreen in a case where the acceptance message is received. In the casewhere the acceptance message is received, an acceptance message (MIKEaccepted mission) 441 is displayed in a lower part of police dispositioninformation 431 in police disposition screen 440. Furthermore, Policedisposition server 20 periodically inquires of device management server40 about positional information of each site terminal 180 and acquiresthe positional information of each site terminal 180, updates currentpolice positional information in every prescribed time, and updates aposition of each police mark on the map of police disposition screen 440which is displayed on center device 80. The example of the drawingillustrates a situation in which police 4 indicated by police mark 424moves toward the target place indicated by target place mark 415 alongpath information 437. Therefore, it is possible for the user in commandcenter 101 to check whether or not the police officer can rush to thetarget place.

FIG. 14 is a view illustrating an example of a navigation screendisplayed on the site terminal. In a case where Police dispositionserver 20 receives acceptance message from the site terminal 180, Policedisposition server 20 sends navigation information, which includes pathinformation until arriving at the target place, to site terminal 180. Ina case where a manipulation to press acceptance button 453 of inquiryscreen 450 is performed, site terminal 180 displays navigation screen460 using the navigation information sent from Police disposition server20. Navigation screen 460 includes map information 461 and route guidingdisplay 462. On the map of map information 461, target place mark 465,which indicates a position of the target place where the incidentoccurs, and current position mark 474, which indicates a position of theterminal, are displayed, and path information 477 from a currentposition of the terminal to the target place is displayed. In routeguiding display 462, a path to the target place is indicated using, forexample, letter information such as “go straight 5 km in a straight lineand turn right 9 km”.

As described above, in cases where the positional information of thesite terminal in the vicinity of the target place, in which the incidentoccurs, is acquired, the position of the police officer is displayed onthe map, and display of the position of the police office isperiodically updated, it is possible to accurately grasp a dispositionsituation of the police officer. Here, pieces of positional informationof the site terminal and the police officer are acquired by efficientlyutilizing the device management server, and thus it is possible to checkthe position of the police officer. In addition, in a case where thepositional information of the site terminal or the shift information ofthe police officer is used, it is possible to accurately narrow down thesite terminals and the police officers which are close to the targetplace. In addition, in a case where the direct rush request check isperformed on the site terminal, which is possessed by the designatedpolice officer and whether or not to rush the site is inquired, it ispossible to grasp the situation of the police officer. In addition, in acase where the police officer receives the direct rush request,navigation information is sent to the site terminal, and thus it ispossible to cause the police officer to accurately rush the incidentoccurrence location. With the processes, it is possible to dispose thepolice officer to the incident site more accurately and rapidly.

In the exemplary embodiment, the terminal information, which includesthe positional information of the site terminal positioned in thevicinity of the target place of the incident occurrence location and thepolice officer information bound to the site terminal, is acquired, thepositional information of the police officer who is close to theincident occurrence location is superimposed on the map information, andthe target place and the position of the police officer are displayed onthe map. Therefore, it is possible to easily grasp the position of thepolice officer in the vicinity of the position of the target place, andit is possible to accurately and rapidly dispatch the police officer tothe incident site.

In addition, in the exemplary embodiment, the police dispositioninformation, which includes the needed distance or the needed time fromthe current position of the designated police officer to the targetplace, is displayed, and thus it is possible for the designated policeofficer to check a distance or time, which is necessary to arrive at thetarget place, and it is possible to accurately and rapidly dispatch thepolice officer to the incident site.

In addition, in the exemplary embodiment, in a case where the directrush request check is sent to the site terminal which is used by thepolice officer and the acceptance message is received from the siteterminal, the acceptance message is displayed. Therefore, it is possibleto check whether or not the designated police officer can rush thetarget place, and thus it is possible to accurately and rapidly dispatchthe police officer to the incident site.

In addition, in the exemplary embodiment, in a case where the directrush request check is sent to the site terminal, the incident-relatedinformation related to the incident is sent, and, in a case where theacceptance message is received from the site terminal, the navigationinformation, which includes path information until arriving at thetarget place, is sent to the site terminal. Therefore, it is possible tosupport the police officer who possesses the site terminal by notifyingincident information and guidance display up to the target place, and itis possible to cause the police officer to accurately and rapidlyarrive.

Third Exemplary Embodiment

An incident information display process of the police work supportsystem will be described as a third exemplary embodiment. A system whichperforms the incident information display process according to theexemplary embodiment may be formed as an incident information displaysystem. In addition, it is possible to prescribe a process procedure inthe incident information display system as an incident informationdisplay method. In the third exemplary embodiment, a process procedureof statistically displaying crime data using a plurality of pieces ofcrime-related information collected from general citizen is illustrated.

FIG. 15 is a sequence view illustrating an example of an operationprocedure of the incident information display process according to thethird exemplary embodiment. The exemplary embodiment illustrates aprocedure performed in a case where incident-related information relatedto an incident, which occurred within the police jurisdiction, iscollected by crime prediction server 30 from SNS server 50 andstatistical crime data is displayed in center device 80 such as clientPC 70.

In FIG. 15, in a case where an incident occurs, a general citizen in aprecinct voluntarily submits incident-related information or otherpieces of information to SNS, and reports the incident. Here, citizenterminal 230, such as mobile terminal 210, inputs submission of SNSinformation according to an information input manipulation performed bythe general citizen (S71), and sends the SNS information to SNS server50 (S72). SNS server 50 receives the SNS information as submissioninformation from citizen terminal 230, and registers the SNS informationin the storage (S73).

Crime prediction server 30 periodically or occasionally accesses SNSserver 50, and sends a request for the crime-related information (S74).Crime prediction server 30 requests SNS information, which includescrime-related terms indicative of a crime type (homicide, burglaries, orthe like), a crime tool (a knife, a gun, or the like), and the like, asthe crime-related information. SNS server 50 extracts SNS information,which includes the crime-related terms, from accumulated SNS informationin response to the request for the crime-related information, outputsthe SNS information (S75), and returns the SNS information to crimeprediction server 30 (S76). Therefore, collection of the crime-relatedinformation is performed by crime prediction server 30. Crime predictionserver 30 registers the collected crime-related information in thestorage (S77), calculates statistical data of the crime-relatedinformation for respective of various attributes, such as a crimeoccurrence place, an occurrence hour, a crime type, and a crime tool,and updates the statistical data of the crime-related information (S78).The crime-related information may include crime tool information as asub-category of the crime type, and the statistical data may becalculated by dividing respective attributes as items.

Center device 80 is capable of displaying a crime-related informationdisplay screen, which realizes an incident information displayinterface, on display 76, and is capable of displaying the crime dataand the statistical information thereof according to a usermanipulation. In a case where a region designation manipulation ofdesignating a region where a police officer or a person in charge who isthe user in command center 101 predicts danger is performed (S79),center device 80 sends a request to deliver map data and crime data tocrime prediction server 30 (S80). Crime prediction server 30 refers topositional information of the crime occurrence place for statisticaldata of accumulated crime-related information, extracts crime data boundto the designated region, and outputs the crime data (S81). Furthermore,crime prediction server 30 superimposes the extracted crime data on mapdata, and delivers resulting data to center device 80 (S82). Centerdevice 80 displays the crime-related information display screen, inwhich the crime data is plotted in a position corresponding to the crimeoccurrence place on the map, on display 76 (S83). Meanwhile, thecrime-related information display screen may be displayed using siteterminal 180 as the client device instead of center device 80. That is,crime prediction server 30 is capable of being coupled to either centerdevice 80 or site terminal 180 as the client device, and is capable ofdelivering and displaying the crime-related information display screenon both or one of center device 80 and site terminal 180.

FIG. 16 is a view illustrating an example of the statistical data of thecrime-related information. Crime prediction server 30 aggregates thecrime-related information collected based on the SNS information foreach of the various attributes, such as a crime type and an occurrencehour of an occurred crime, for each crime occurrence place. The exampleof the drawing illustrates an example of statistical data which isacquired by classifying each of a place A and a place B into a crimetype (homicide, burglaries, or the like) and an occurrence hour(morning, afternoon, midnight), and aggregating the data respectively.With the statistical data, it is possible to acquire statistical crimeoccurrence situation information which indicates a type of a crimeoccurred in a specific place in a specific time slot.

FIG. 17 is a view illustrating a first example of the crime-relatedinformation display screen. The first example is an example in whichcrime data in a prescribed region is displayed for each of the pluralityof attributes. Crime-related information display screen 500 according tothe first example includes map information 501 and crime attributeinformation 502 which is disposed in a left end part of the screen. Incrime attribute information 502, a crime type list (homicide,burglaries, sexual assault, robberies, drug crime, and the like) 511 anda crime tool list (a knife, a gun, others) 512 are displayed as a list,such that the user can select an attribute displayed as the crime data.On the map of map information 501, crime occurrence marks 521, 522, and523, which are colored for respective attributes, are plotted anddisplayed in crime occurrence places. In a case where a radio button anda check mark, which are provided besides a crime type list and a crimetool list of crime attribute information 502, are designated asattribute designation inputs by the user, the crime occurrence marks ofcorresponding attributes are displayed on the map. In a case where theradio button and the check mark are not designated, the crime occurrencemarks of the corresponding attributes are not displayed. In a lower endpart of map information 501, time slot designation bar 531, whichdesignates a time slot of crime occurrence hours to be displayed, isdisplayed. In the example of the drawing, crime data in crime occurrencehours of 0:00 to 13:00 is illustrated through designation of time slotdesignation bar 531.

In FIG. 15, in a case where a manipulation of selecting crime type list511 or time slot designation bar 531 is performed by designating a crimetype or a time slot desired to be displayed on a screen as attributedesignation input performed by the user (S84), center device 80 sends aninstruction to select the crime type or the time slot to crimeprediction server 30 (S85). Crime prediction server 30 performsnarrowing-down based on the attributes of the statistical data of thecrime-related information according to the instruction to select thecrime type or the time slot (S86), and delivers the crime data acquiredthrough narrowing-down to center device 80 (S87). Center device 80displays the crime-related information display screen, in which thecrime data acquired through narrowing-down based on the designatedselection condition is plotted on the map, on display 76 (S88).

FIG. 18 is a view illustrating a second example of the crime-relatedinformation display screen. The second example is an example in whichcrime data in a prescribed region is displayed after being narrowed downto a specific crime type. In crime-related information display screen520 according to the second example, only crime occurrence mark 545corresponding to a crime type list 541 of a robbery which is instructedto be selected is displayed on the map. In a case where a crime type anda crime tool, which are desired for the user to display, are selected,it is possible to narrow down the crime data to be plotted anddisplayed, and it is possible to check an occurrence situation of aspecific crime type (robbery in the example of drawing).

FIG. 19 is a view illustrating a third example of the crime-relatedinformation display screen. The third example is an example in which thecrime data in the prescribed region is displayed after the crimeoccurrence hours are narrowed down to a specific time slot. Incrime-related information display screen 540 according to the thirdexample, only crime occurrence mark 546 in crime occurrence hours of2:00 to 4:00 is displayed on the map so as to correspond to time slotdesignation bar 532 of 2:00 to 4:00 in which selection time slots narrowdown. In a case where a time slot desired to be displayed is selected bythe user, it is possible to cause crime data, which is plotted anddisplayed, to narrow down, and thus it is possible to check a crimeoccurrence situation in the specific time slot (midnight in the exampleof the drawing). As in the display examples of FIG. 18 and FIG. 19, itis possible to display only crime data, which coincides with a relevantcrime occurrence condition, and to display statistical data, which isnecessary for the crime occurrence prediction, in such a way that theuser selects the display attribute.

In FIG. 15, in a case where the user designates a crime occurrence markof specific crime data whose statistical information is desired to bedisplayed on the screen and a statistical display manipulation of thedesignated place is performed in order to instruct statistical display(S89), center device 80 sends a statistical display request to displaythe statistical information to crime prediction server 30 (S90). In acase where crime prediction server 30 receives the statistical displayrequest, crime prediction server 30 inquires of center device 80 aboutan axis of a graph including a time axis and a type axis in order toperformed statistical display, and outputs statistical display data ofstatistical information of the crime data which is extracted accordingto the axis of the graph of a selected display mode (S91), and deliversthe statistical display data to center device 80 (S92). Center device 80displays a statistical information display screen, in which statisticaldisplay data of the graph is superimposed on the map, on display 76(S93).

FIG. 20 is a view illustrating an example of the statistical informationdisplay screen. In statistical information display screen 560, pieces ofstatistical information 561 and 562 are displayed which are formed asgraphs by statistical display data of crime-related information (crimedata) in the respective places with respect to crime occurrence marks551 and 552 which are plotted on the map. In statistical informationdisplay screen 560, it is also possible to narrow down time slots of thecrime occurrence hours which are displayed through designation of timeslot designation bar 533. The pieces of statistical information 561 and562 of the example of the drawing are formed as graphs by makingcrime-related information at specific places be type axes. Ratios ofoccurrence frequencies for respective crime types with respect to crimedata of two spots (Place #A and Place #B) in a time slot, in which thecrime occurrence hours of 18:00 to 23:00, are illustrated using piegraphs. Meanwhile, it is possible to perform display in such a way thata graph axis of the graph which is displayed as the statisticalinformation is set to a time axis and an occurrence situation for eachtime slot with respect to the whole crime type or a specific crime typeis formed by a graph.

As described above, in a case where pieces of SNS information which aresubmitted by a plurality of unspecified citizens are acquired, pieces ofcrime-related information are collected based on the pieces of SNSinformation, and statistical data of the pieces of crime-relatedinformation is generated for each of the various attributes of anoccurred crime, it is possible to acquire data which statisticallyindicates the crime occurrence situation for each attribute. Here, it ispossible to accumulate the statistical data by occasionallyincorporating the crime-related information including the crime-relatedterms from a large amount of information which includes lowly accurateinformation submitted by general citizens, and it is possible togenerate the statistical data, in which the crime-related information isaggregated, using a simple method. In addition, in a case where thecrime data divided into categories is superimposed and displayed on themap, it is possible to intuitively determine the crime occurrencesituation, and it is possible to predict a crime occurrence tendency foreach attribute, such as the crime occurrence place, the crime type, orthe occurrence hour. In addition, in a case where the statisticalinformation of the crime-related information is displayed, it ispossible to intuitively recognize the crime occurrence situation of eachplace using the graph, and it is possible to easily grasp the crimeoccurrence tendency.

With the above-described incident information display process, it ispossible to support the crime occurrence prediction performed by apolice officer or the like, it is possible to improve the accuracy ofthe crime occurrence prediction, and it is possible to contribute toreduce crime and to contribute to improve the safety of a region. Inaddition, it is possible to appropriately set a time slot and a locationwhere the police officer performs patrol by plotting and display on themap, which shows the crime occurrence situation, or using thestatistical information, thereby achieving patrol efficiency. Meanwhile,for example, crime prediction server 30 is interconnected with Policedisposition server 20, a police officer patrol region and a time slotare determined according to a result of the crime occurrence prediction,and thus it is possible to support preparation of a police officerdisposition plan.

In the exemplary embodiment, submission information, which includes thecrime-related terms, is collected as the crime-related information fromsubmission information of the general citizens by accessing the SNSserver, statistical data with respect to the crime-related informationis calculated for each attribute which includes the crime occurrenceplace, the occurrence hour, and the crime type, the crime data for eachattribute is superimposed on the map data, and the crime data is plottedand displayed in a position corresponding to the crime occurrence placeon the map. Therefore, it is possible to intuitively determine the crimeoccurrence situation in a prescribed region, and it is possible toaccurately and easily predict the crime occurrence tendency or the likefor each attribute using the plurality of pieces of incident-relatedinformation.

In addition, in the exemplary embodiment, in a case where the crime datais displayed, crime data is displayed which is narrowed down to adesignated attribute according to attribute designation input performedby the user. Therefore, it is possible to check the crime occurrencesituation under a specific condition according to the designatedattribute, and it is possible to minutely perform the crime occurrenceprediction.

In addition, in the exemplary embodiment, in a case where thestatistical display data of the crime data is output using a displaymode according to the statistical display request, and the statisticalinformation of the crime data is displayed. Therefore, it is possible tointuitively recognize the crime occurrence situation of each place usinga graph or the like, it is possible to easily grasp the crime occurrencetendency, and it is possible to improve convenience of the crimeoccurrence prediction.
